aazzwaom'mdy 00mm.; Y .Be it known that LADOLPH- Nnneenma .citiznifof `the United'gStates, and resident o'lililwaukee, 'inthe' county 'of Milwaukee :rand-S'tate of Wisconsim: havey invented cer` tainnew [and useful Improvementsin Bilgef Pumps;` and I do hereby declare that the followingisa full, clear, andexact descripf' z I' 13 bolted-transversely onone'end/of' the.

present 4lmentipn relates.- to new and; improvements Q in portable. bllgeA pumps,v more particularly of that. type in.- cluding 'a diaphragm having a centrallyI disposeddischargejyalve,I'

.I'It .'sin general the object'of my vmvention to simplifyand otherwise improve .the-

structure, and to increase the-.eiiciency of pumps of this natur'e. f v. v

-fMore` particularly, itis lanv important ob-V ject'to provide a worm gear .I drivefmeans for thev pump, wherebyxa maximum. com:- pactness of structureis'.;procured,;and further' whereby al drive means. may vbe lehicientlyhoused. Y y

`-Afi11tl 1'er important object residesin the provision of a convenient general assembly for thepump. and its drive engine whereby 'both the v'pump 'and the A.engine 'areailorded fan integral common base, and'it. is in 4this connection more f specically an. object; to utilizesaid s portions` ofr 'the englne ew, the..l invention resides .more particularly in the novel combination,

Y 27 passing through-an intermediateflangef portion thereof, and the-other side wall portion.l is providedfwith--a bleed-. Opening 28 for' the chamber. The inner endv ofv the ni] op'l e; is.horizontally elongatedto form a with this seat. is ag' valve lseat and 'coacting exihle inlet valve plate 29 secured by the screws .29" to' the upper side of the'seat and'y having stillenin'g and weighing plates 80 bolted to its lower portion. Secured by.l

bolts 31 to the bed plate in registry vwith the Vinlet chamber aperture 24' is an upstand-- .ing lcylindrical vcasing from .oneside of .which proj ectsan 'outlet spout 33'. vThsupper..l

f portion of that side ofthe casingpf'adjacent the pump shafty is bifurcatedfto'f-.formfinner' and'outer wall portions-dening theijlnyv'egportion of the gearcasin ftof. the'. andthe pumpl carried sha t 21' whichjis to theengine'shaft. is carnale@ iiifbear, l l l ing'blocks 35 bolted to the lower open ends of said casing, and closing said casing whereby its lower portion forms an oil tight well. ,An upper casing portion 36 is bolted to said lower portion and these casing portions form split journals for a valve actuating crank Shaft 37; rlhis shaft carries within the casing a worm gear 38 meshing with a worm 39 on the shaft 21.

The flexible diaphragm 40 of the pump is disposed over the aperture 24 of the body casting and is secured in place by the disposition of its edges between the cylindrical'.

diaphragm clamping rings 44 and 45 lrespectively which are preferably provided `with Voutwardly inclined annular flange portions whereby to relieve strain from the diaphragm. The lower clamping ring is provided inwardly of the upper ring with an upstanding annular flange 46 and this flange serves ,to direct the inner edge of the diaphragm upwardly when clamped between the rings to form a seat for the valve head 47. This xvalve headis guided in its movement by depending lingers 48 slidable within the lower clamping ring and by a central upstan'ding pin 49 slidable through a connecting bar 50 of the lower ends of the pitman arms4 Disposed on this rod isa spacing sleeve l whereby the unseating movement of the valve head is limited.

From the foregoing description it is seen that an exceedingly simple ellicient and compact bilge pumpl has been provided wherein a practically noiseless'drive ispro- *cured by the worm 39 and gear 38. Attention is particularly directed to the ease and convenience with which vthe `various parts of the pump may be assembled and disassembled, as the entiregoutlet valve'mecha- Leaaasi nisni including the casing 3i? may he removed by detaching the bolts 3l which secure it to the bed casting, and detaehing the bolts of the flexible shaft coupling, this de tachment also providing for the removal or insertion of the diaphragm. By utilisingA the interior'of the vbed casting as portiens of the pump and engine, an exceedingly compact combined structure is procured, and at thesame ltime a proper relativel positioning of the'engne and pump is assured.

What is claimedis:

l. -A combined-engine and bilge .pump

lstructure comprising" a single bedl casting having chambers formed in its end portion, an engine secured tothe bed pump over -one ,of the chambers, a pump casing secured to the casting over the other chamber, said other chamber forming the inlet compartment of the pump and the first named chamber. forming the fuel supply tank' of the engine.

2.. A combined bilge, pump and engine structurecomprising a single bed castingv having a chamber'in one end, a casing secured thereto in registry with the chamber, a diaphragm disposed between the chamber and casing and centrally apertured, clamping rings bolted to the diaphragm adjacent its aperture, a crank shaft extended transversely of the casing, a flexible connection between the engine and crank shaft, a pit- .man connecting said crank shaft and rings,

a valve slidably mounted within the rings, al centrally upstanding pin carried lby the valve and slidable in a `guide opening in said pitman for guiding said valve, and a spacing sleeve disposed on said pin whereby' the upward movement of the valve is limited, substantially as described.

In testimony that l claim the foregoing I have hereunto set my hand at Milwaukee, in the. county of Milwaukee and State of l/Visconsm, in the presence of two witnesses.
